concern: Be it known that I, ALBERT O. BUonIUs,

, J r., of Chicago, Cook count Illinois, have invented anew and useful mprovement in Truck Side Frames, of which the following 'is a full, clear, and exact description, reference being had to the accompanying draw- -in the seats formed by the under side of ings, forming part f this specification, in which-'- Figure 1 is a side view of'a truck side fram'e embodying my invention; Fig. 2 is a .bottom plan view; and Fig. 3 is an end view.

' My invention has relation to certain new for-cars, the' present application being a and useful improvements in truck frames division of my pending application Serial NO. 581,464, fi ed September 10th, 1910. Y

The object of my invention is to provide the side frames of a car truck with means 0f s1mple, novel and efliclcnt character for securing the journal boxes thereto. My invention'provides 'means of this character, in which the journal boxes are firmly held, both laterally and vertically, to their seats on the sideframe, and secures all'the advantages of a construction in which the journal boxes are cast integrally with the side frame without any of the disadvantages of such a construction.

Referring to the accompanying drawings the numeral 2 desi ates the side-frame o the car-truck, whic is provided at its ends with the overhanging portions 3. 4

4 are the journal boxes, which are held these overhanging ortions 3 and by the vertical end Walls 0 the side frame proper. The journal boxes are preferably provided with ribs or flanges-5 at the top to engage the sides of the overhanging portions 3.

The journal boxes are secured in place by means of a truss member or red 6, which extends underneath the side frame, being provided at its central portion with suitable iearings at 7 upon the bottom of the Side threaded to receive securin and 'nd'ustins.

nuts 8, these nhts being preferably seated between the side flanges 2? of the portions 3. The journal boxes are-alsopreferably provided with suitable flanges 9. to form seats or guides for the member 6.- The boxes areshown as having convex lower portions around which the member 6- is' Patented J une vertical seating faces at the ends of the side frame.

By the construction described Iprovule means whereby the journal boxes may be.

rigidly secured in place, but which will permit their ready removal when desired. This gives a. construction which has all the advantages of a construction in which the boxes are cast integral with the side frames, but which avoids the difficulties due to yariations in the shrinkage of metal. It

also provides aconstruct-ion in which either one of the boxes can be readily removed and replaced when necessary, which is not possible with the integral construction. It also permits ,the ready removal of the wheels and axleis, together with the boxes, from the side frames, when desired.

What I claim is:-

1. In a truck frame, a side member having overlmnginp end portions pri'n'idcd with journal box seats at the under side thereof, and a securing member extending longitudinally -m dcrncath the side frame and having its end portions secured in theoverhanging portions of the truck frame, said member being adapted to engage the journal boxes and hold them to their seats; substant-ially as described.

2. in a truck frame, a side member having overhanging end portions provided with journal box seats atthe under side thereof, and a securing member extending longi- .tndinally underneath the side frame and having its end portions adjustably secured in the overhanging portions of the truck frame, said member beingadapted to engage the journal boxes and hold them to their seats: substantially as described.

3. In a truck frame, a side member having vertical journal box seating portions at its end, and also having overhanging portions extending beyond said seating porjournal box seats at its end portions, said ring at the under side thereof at its' central portion, the ends of the member extending upwardly into the overhanging portions of the'frame and secured therein, said rod bejn arranged to engage journal boxes and 1101 them firmly against their seats; substantially asdescribed.

' la-In a car truck, a side framehaving seats being openvat' the bottom and outer j sides, boxes 1n saidseats, and a continuous seats being open at the securing member embracing the outer and lower sides of the boxes and securing them to their seats; substantially as described.

7:5. In a car truck, a side frame having journal "box seats at its endportions, said bottom and outer sides, boxes 111 said seats, and a continuous securing member embracing the outer and lower sides of the boxes and securing them to-their seats, said member having a bearing at its central'poi'tion upon the under side of the side frame and having its end portions secured in the end portions of the side frame; substantially as described.

6. In a -car truck, a side frame havin ournal box seats at its end portions, said seats being .0 en at the bottom and outer sides, boxes 1n said seats, and a continuous securing member embracing the outer and lower sides of the boxes and securing them to their seats, said member having a bearing at its central portion upon the under side of the side frame and having its end portions secured in the end portions of the side frame, and the boxes having grooves or guides to receive the member; substantially as described- 7. A truck side frame having at each, end two hearing faces at an angle to each other, journal boxes seated against said faces, and a continuous securing member engaging the boxes and arranged to draw both of them upwardly and inwardly against said faces; substantially as describe In testimony whereof, I have hereunto set my hand.
